AUTO REPAIR

This function automatically repairs gaps and improves element quality in the mesh by merging nearby nodes and modifying elements. Caution should be taken when this function is selected as it can change the geometry of the tooling. Several user-defined control options are given for identifying and repairing the inferior mesh. After selecting elements, the REPAIR PARAMETERS dialog box as illustrated in Figure 5.3.27 is displayed.

PRIORITY

The user can set the priority to split QUADs into 2 or 4 Triangles, and take FEATURE LINE or WARPAGE into account when doing the repair.

The user can select SHORT EDGE and/or SHARP EDGE.

 

PARAMETERS FOR CHECKING BAD ELEMENTS

These parameters are the criteria for repairing bad elements: MINIMUM ELEMENT SIZE (DTOL), SHARP ANGLE TOLERANCE (ATOL), LARGE ANGLE TOLERANCE (CA_TOL), WARPAGE TOLERANCE (W_TOL), FEATURE LINE ANGLE TOLERANCE (F_TOL), and GAP TOLERANCE (GAP_TOL).

 

After the necessary parameters are defined, click OK to perform mesh repair.  The selected mesh will be checked and repaired according to the defined criteria.  The program will display the repaired mesh and prompt for acceptance.
